Description

Straparollus planodorsatus (Meek & Worthen, 1860) - fossil snail from the Mississippian of Ohio, USA. (apical view; ~2.0 centimeters across at its widest)

The Maxville Limestone is the only Middle to Late Mississippian-aged stratigraphic unit in Ohio. Its outcrop belt is not extensive - it principally occurs in Muskingum County and Perry County in eastern and southeastern Ohio. The Maxville Formation can also be found as cobbles and pebbles in the basal Sharon Formation (Lower Pennsylvanian), which disconformably overlies Ohio's Mississippian rocks. Paleohills, or erosional outliers, of Maxville Limestone have also been identified.

This fossil snail has eroded free from calcareous shale host rock derived from the Maxville.
